Cannabinoids Generally. Cannabinoids are chemical compounds that bind to certain cannabinoid receptors in the body, producing physiological effects. The cannabis plant contains many different cannabinoids, of which tetrahydrocannabinol (THC) and cannabidiol (CBD) are most common. Both THC and CBD have the same molecular structure, but a different arrangement of individual atoms - referred to as isomers in chemistry - which results in differing effects on the body. THC has a number of individual isomers, such as delta-8 THC, delta-9 THC, delta-10 THC. THC is often understood as being only delta-9 THC, however, the cannabis plant contains over 80 different cannabinoids.
Hemp, Marijuana, and Federal Law. Both hemp and marijuana are derived from the cannabis plant and both contain THC and CBD, in varying concentrations. There is a legal distinction between hemp and marijuana. The Agriculture Improvement Act of 2018 (Farm Bill) defined hemp as cannabis with a THC concentration of 0.3 percent or less, and marijuana as cannabis with a THC concentration of more than 0.3 percent THC. The Farm Bill also removed hemp from the definition of marijuana in the federal Controlled Substances Act (CSA). In 2020, the federal Drug Enforcement Administration (DEA) issued an interim final rule to align the Farm Bill with the CSA. DEA stated that all synthetically-derived THCs remain Schedule I controlled substances under the CSA.
Conversion by Chemical Synthesis. One isomer can be converted into another by chemical synthesis through the use of a catalyst. For example, CBD can be converted into THC, whether delta-8, 9, or otherwise. In addition, delta-8 THC can be converted into delta-9 THC.
Washington Law. In Washington State, the Washington State Department of Agriculture (WSDA) regulates hemp and the Washington State Liquor and Cannabis Board (LCB) regulates adult-use, recreational marijuana. LCB and the Washington State Department of Health (DOH) jointly regulate medical marijuana.
Definitions. "THC concentration" means the percent of delta-9 THC content per dry weight of any part of the plant Cannabis, or per volume or weight of marijuana product, or the combined percent of delta-9 THC and THC-acid in any part of the plant Cannabis regardless of moisture content. THC is not separately defined under state law. The state law definition of "marijuana" includes only the concentration of delta-9 THC. "CBD product" means any product containing or consisting of CBD.
Liquor and Cannabis Board Regulation. On April 28, 2021, LCB adopted a policy statement outlining its position on the regulation of THC, other than delta-9, and the conversion of CBD, hemp, or both to delta-8, 9 THC, or any other cannabis compounds not contained in state law. Based on the unknown health implications, LCB prohibited delta-8 THC and its derivatives, extracts, cannabinoids, isomers, and hemp CBD isolate that are genetically or chemically altered into compounds from being produced or processed in LCB-licensed facilities, or being sold in licensed marijuana retail stores. On May 3, 2021, LCB issued a statement clarifying the April 28, 2021, policy was only advisory until it completed rulemaking. On January 5, 2022, LCB approved permanent rules allowing the agency to evaluate additives, solvents, ingredients, or compounds used in the production of marijuana products and prohibiting the use of substances determined to pose a risk to public health or youth access.
License Authorizations. A marijuana producer licensee may produce, harvest, trim, dry, cure, and package marijuana into lots for sale at wholesale to marijuana processor licensees and to other marijuana producer licensees. The licensee may also produce and sell certain marijuana plants and seeds, immature plants, clones, and seeds to other marijuana producer licensees, registered cooperatives, qualifying patients, designated providers, and licensed cannabis researchers, under certain circumstances. Producer licenses are designated by tier, which relates to the size of marijuana production. A marijuana processor licensee may process, dry, cure, package, and label usable marijuana, marijuana concentrates, and marijuana-infused products for sale at wholesale to marijuana processors and retailers. A marijuana retailer licensee may sell usable marijuana, marijuana concentrates, marijuana-infused products, marijuana paraphernalia, and lockable boxes to store marijuana at retail in outlets to individuals 21 or older, unless authorized by the Washington State Medical Use of Cannabis Act.
Quality Control Testing. State law requires every licensed marijuana producer and licensed marijuana processor to submit representative samples of marijuana, usable marijuana, and marijuana products produced or processed by the licensee to an independent, third-party testing laboratory meeting certain accreditation requirements, for inspection and testing to certify compliance with specified quality assurance and product standards. If the product sample fails one or more tests, the entire lot from which the sample was taken must be destroyed. LCB rules outline laboratory certification and accreditation, quality assurance sampling protocols, and quality assurance testing. On December 8, 2021, LCB indicated a public hearing will be held on February 2, 2022, relative to proposed amended rules on testing.
Product Additives. State licensed marijuana producers and processors are unrestricted in their use of CBD products for the purpose of enhancing the CBD content of regulated marijuana products, provided such CBD products are lawfully produced by or purchased from an in-state producer or processor licensed by the LCB. Licensees may also use CBD products for CBD enhancement purposes even if imported or otherwise produced outside of the LCB regulatory system provided the CBD product has:
Safe Harbor. State law provides certain protections from criminal and civil liability for authorized activities performed by licensed marijuana producers, processors, and retailers. These protections are also extended to the employees of such licensees.
New Definitions. "Cannabinoid" means any of the chemical compounds that are the active constituents of the plant cannabis, including several listed examples. Definitions are provided for a number of individual cannabinoids, such as delta-7 THC, delta-8 THC, delta-9 THC, delta-10 THC, and others.
"Artificial cannabinoid" means a cannabinoid that possesses either a similar chemical structure to any naturally occurring cannabinoid or exhibits agonist activity at one or more cannabinoid receptors and is not found in nature.
"Naturally occurring cannabinoid" means a cannabinoid found in the plant Cannabis.
"Impairing cannabinoid" means a substance containing a similar structural backbone to THCs and THC-similar molecules, which possesses significant binding activity to the human body's cannabinoid receptors, and results in reliable functional impairment.
Amended Definitions. The definition of "manufacture" is amended to exempt licensed marijuana processors performing authorized activities in the bill.
"Marijuana processor" is amended to authorize the conversion of cannabinoids derived from the plant Cannabis into naturally occurring cannabinoids.
License Authorizations. The marijuana processor's license is expanded to authorize processing and use of cannabinoids derived from hemp and hemp derivatives, which are then added to marijuana products authorized for production, processing, and sale under the Washington State Uniform Controlled Substances Act (UCSA). Licensed marijuana processors may use hemp and hemp derivatives obtained from a source not licensed by LCB if the hemp and hemp derivatives:
Safe Harbor. The bill's authorized use, possession, processing, packaging, labeling, delivery, distribution, and sale of hemp and hemp derivatives is not a criminal or civil offense under state law.
Quality Control Testing. All marijuana producers, processors, certified labs, and certified lab employees must comply with specified marijuana testing requirements that include potency testing, residual solvent screening, heavy metals screening, and pesticide screening. Certain marijuana products require additional testing, such as potency analysis, moisture analysis, foreign matter screening, microbiological screening, mycotoxin screening, pesticide screening, and heavy metals screening. Usable marijuana, marijuana concentrates, and marijuana-infused products may not be sold or transported until the required testing is completed and passed. Exceptions are provided for certain business entities, and wholesale sales and transfers of certain products.
Liquor and Cannabis Board Rulemaking. LCB may adopt rules pertaining to laboratory testing, product safety standards, and labeling for hemp and hemp derivatives used by licensed marijuana processors. Other limitations on rulemaking are provided. LCB must adopt rules regarding statistical sampling procedures and to provide a remediation process for licensees when their marijuana products fail required quality control tests.
